BETHLEHEM, Pa. -- Intrigue was added to the Eagles' No. 2 quarterback competition on Saturday after coach Andy Reid revealed that Mike Kafka fractured his left hand and will not be able to fully participate for three weeks.

Kafka, the third-year backup quarterback, had his non-throwing hand stepped on during Thursday's 24-23 win over the Pittsburgh Steelers in the preseason opener. Kafka will be take part in 7-on-7 drills and some individual drills, but will not be able to participate in any drills that require him taking snaps. Reid estimated a recovery time of three weeks.

We’ll see how that all works out," Reid said. "Keep an eye on it as we go"

Kafka could be seen with his left hand wrapped after Monday's walk-through, although he was rushing to a meeting and did not have time to comment on the injury.

Reid also said that rookie Nick Foles will take the snaps with the second-time offense in Kafka's absence.

Foles outplayed Kafka on Thursday. The rookie went 6-for-10 with 144 yards and two touchdowns. Kafka went 5-for-9 with 31 yards and an interception.
